System integration
Integration and compatibility
Use these checks to connect ITR3CMOS21000KPA to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Lens and microscope interface
- Lens Mount: C-mount
- Use a lens image circle that covers the sensor and check flange distance before adding C/CS, F-mount or M42 adapters.
- Sensor and sampling
- Sensor: Sony IMX269AQR · Resolution: 21MP (5280×3954)
- Match pixel pitch to the diffraction-limited spot the optics deliver. Sampling finer than the optics resolve multiplies data volume without adding information; sampling coarser discards resolution you have paid for.
- Interface and data rate
- Frame Rate: 17 fps @ 5280×3954; 17 fps @ 3952×3952; 56 fps @ 2640×1976; 67 fps @ 1760×1316; 192 fps @ 584×438 · Interface: USB3.0
- Confirm the host can sustain the interface bandwidth continuously, not in burst. A camera that outruns the write path stalls acquisition rather than dropping quietly to a lower rate.
- Hardware synchronization
- GPIO: 1x optically isolated input, 1x optically isolated output, 2x non-isolated I/O ports
- Confirm edge polarity, pulse-width limits and whether each line is opto-isolated before connecting TTL or GPIO signals. A software exposure command is not equivalent to a hardware trigger.
- Cooling and noise floor
- Dynamic Range: 72 dB
- Judge these figures at the exposure time you will actually use. Cooling matters where dark current accumulates over seconds; read noise dominates short exposures where it never does.
